The batting average of a baseball player is classified as a numeric continuous variable.
<h3>What are categorical and numerical variables?</h3>
- Categorical variables assume labels, for example, good or bad.
- Numerical variables assume numbers, as it own name says.
A batting average is given by the <u>number of hits divided by the number of at bats</u>, hence it is a numeric value.
<h3>What are continuous and discrete variables?</h3>
- Continuous variables assume real values.
- Discrete variables assume integer values.
The batting average is a real number, hence it is also a continuous variable.

Step-by-step explanation:
<em>x - is the side of the square</em>
<em />![x^{2} +x^{2} =(10\sqrt{2})^{2} \\2x^{2}} =200\\2x^{2} \div 2=200 \div 2 \\x^{2} =100\\x=\sqrt{100} \\x=10 \: [cm] - side \: of \: a \: square](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2Bx%5E%7B2%7D%20%20%20%3D%2810%5Csqrt%7B2%7D%29%5E%7B2%7D%20%20%5C%5C2x%5E%7B2%7D%7D%20%20%3D200%5C%5C2x%5E%7B2%7D%20%5Cdiv%20%202%3D200%20%5Cdiv%20%202%20%5C%5Cx%5E%7B2%7D%20%3D100%5C%5Cx%3D%5Csqrt%7B100%7D%20%5C%5Cx%3D10%20%5C%3A%20%20%5Bcm%5D%20-%20side%20%5C%3A%20of%20%20%5C%3A%20a%20%5C%3A%20square)

Chebyshev came up with the
limits on how much or how many of the data must lie close to the mean. In specific
for any positive k, the proportion of the data that lies within k standard
deviations of the mean is at least: <span>
1 - 1/k²
<span>In this problem the
mean is 47 yrs therefore:
(47 – 17.3) = 29.7 = (76.7 - 47) </span></span>
The value of k is
calculated using the formula:<span>
29.7 / 11 = 2.7 = k</span>
So the % of gym members
aged between 19.4 and 76.6 is: <span>
1 - 1 / (2.6)² = 0.863 = 86.3 %</span>
<span>Therefore 86.3% of the
gym members are aged between 19.4 and 76.6</span>
